I'm very new to PowerApps, like I started this morning new... I have a custom list in SharePoint Online which will be used to request large expenditure purchases. Part of this list is where users can enter up to 20 "line item" amounts, as well as a "Total Amount" value. All 20 line item amounts must equal the value they entered into the Total Amount field, or it should throw an error. I've been playing around this afternoon just getting familiar with this platform, and as of now, I have no idea how to tackle this. Any ideas would be greatly appreciated!
